Hi, I'm using S21+. After the recent phone update, I noticed that the screen on time indicator in the battery has been shorten drastically. Example, with battery of 73%, the screen on time is only 1hr 33min.
My friend having the same S21+ but she didn't update her phone, the battery of 78%, the screen on time is 6hr 30min.
Why there is such a huge different after the phone being updated?
